Manage Defined Spend (MDS), a new AdWords tool, enables advertisers to build and apply budgets under a single service agreement.

AdWords already permits advertisers to build and manage separate ad budgets under multiple service agreements. MDS instead enables users to build out "child" accounts under a single "parent" agreement.

The new option will appear under My Client Center. A button to the right marked "Modify Budget" gives clients access to the MDS.

Child account shells cannot be created directly on the site. AdWords users must access a Google representative to create them. According to AdWords consultant Shimon Sandler, Quality Scores and Account Histories will not be affected.

Invoices can also be consolidated and downloaded directly from the interface.
